AI Technical Summary
Technical Problem
The electrode spacing between traditional liquid metal magnetic fluid generators is small and the output voltage is low, making it difficult to meet the needs of efficient power conversion.
Method used
The insulating flow guide assembly is used to divert the liquid metal and cut the magnetic field magnetic force lines to form a parallel flow field, and the electrode spacing is increased through the short-connection and series structure of the first electrode pair and the second electrode pair to block leakage current.
Benefits of technology
The output voltage and output power of the magnetofluid generator are increased under low flow velocity conditions, achieving efficient power conversion.

Abstract
The invention relates to the technical field of generators, and discloses a liquid metal magnetohydrodynamic generator, comprising: a housing having a flowing space of liquid metal, and an inlet and an outlet communicated with the flowing space; at least one pair of magnets which are oppositely arranged and have opposite polarities form a magnetic field which is distributed along the axial direction parallel to the shell in the flowing space of the shell; the insulating flow guide assembly is arranged in the flowing space in the axial direction of the shell and is suitable for shunting the liquid metal flowing in from the inlet and cutting magnetic lines of the magnetic field towards at least two different directions; the first electrode pair and the second electrode pair oppositely penetrate through the shell, two electrodes of the first electrode pair and the second electrode pair are evenly arranged on the two sides of the insulation flow guide assembly, the parts, located outside the shell, of the positive electrode and the negative electrode of the first electrode pair are arranged in a short circuit mode, and the parts, located outside the shell, of the positive electrode and the negative electrode of the second electrode pair are connected with a load. The magnetohydrodynamic generator solves the problems that an existing magnetohydrodynamic generator is small in electrode distance and low in output voltage.
